Description: Value of the divides relation. (Contributed by Mario Carneiro, 1-Dec-2014.)

Hypotheses

Ref	Expression
dvdsrvald.1	|- ( ph -> B = ( Base ` R ) )
dvdsrvald.2	|- ( ph -> .|| = ( ||r ` R ) )
dvdsrvald.r	|- ( ph -> R e. SRing )
dvdsrvald.3	|- ( ph -> .x. = ( .r ` R ) )

Assertion

Ref	Expression
dvdsrd	|- ( ph -> ( X .|| Y <-> ( X e. B /\ E. z e. B ( z .x. X ) = Y ) ) )

Distinct variable groups:   z, B   z, X   z, Y   z, R   z, .x.   ph, z

Allowed substitution hint:   .|| ( z)

Proof of Theorem dvdsrd

Dummy variables x y are mutually distinct and distinct from all other variables.
